Cox proportional hazards model analysis showed that TREM2 expression levels were associated with OS in CESC (p = 0.030), lymphoid neoplasm diffuse large B-cell lymphoma (DLBC) (p = 0.009), KIRC (p = 0.022), KIRP (p = 0.009), brain lower grade glioma (LGG) (p = 0.001), LIHC (p = 0.002), LUAD (p = 0.036), skin cutaneous melanoma (SKCM) (p = 0.027), and THCA (p = 0.045) (Figure 3A). Here, TREM2 is linked to diffuse large B-cell lymphoma.
